Fig. 3: CFD simulation of N2O flow regime.
From: High single-pass conversion of nitrous oxide to dinitrogen in gas-diffusion-electrolyzer
N2O flow velocity along the electrode surface for (a) GDE and (b) H cell at 1 s and 7 s, and the N2O volume fraction along the electrode surface for (c) GDE and (d) H cell at 1 s and 7 s. The N2O flow velocity and volume fraction along the red line varies with distance for (e) GDE and (f) H cell. g Scheme of gas diffusion kinetic from flow channel to gas–liquid–solid triple-phase boundary. h N2O ideal diffusion rate and decomposition rate at −1.4 V vs RHE of different inlet concentrations.
